Is drywall toxic to soil?
However, when drywall reaches landfills--and it does so in vast quantities, as it constitutes about 15% of all construction and demolition debris--it can leach these toxic chemicals into groundwater. And in the anaerobic conditions of landfills, bacteria convert gypsum into hydrogen sulfide, a poisonous gas.

What happens if you bury drywall?
Under oxygen-depleted conditions, such as in a landfill or several feet underground in a covered hole, the gypsum (calcium sulfate) in drywall can decompose to release the noxious gas hydrogen sulfide. This gas is hazardous at high concentrations and an odor problem even at very low levels.

Does gypsum decompose?
Sulfate-reducing bacteria convert sulfates to toxic hydrogen sulphide gas; they are killed by exposure to air, but the moist, airless, carbon-containing environment in a landfill is a good habitat for them. So gypsum put into landfill will decompose, releasing up to a quarter of its weight in hydrogen sulfide.

Sheet rock dust will be hard on the bearings on what ever you put it through. It is so fine, it gets into places you didn't know you had places. When our house was built, we threw chunks onto the garden spot. Roto-tilled, disked, etc. In a couple of seasons it was gone. The moisture in the soil keeps the dust down.

i used our slinger put a bunch of peices in the bottom and then dumped some manure on top ran it for a bit then opened the door just enough to let it out worked great plus dont get all that dust
TroyDairy
We've used scrap dry wall for bedding. If you toss chunks into our 8018 Knight slinger they disappear when mixed with sawdust. A local guy used to recycle lots of it with scrap wood when construction was hot and we would buy it for bedding.
TroyDairy
Yeah you aint exactly going to get miraculous yields from it! But bett than paying for the dumpster to take it.
brewcrew
Yeah, I'm not exactly sure what good it will do, but I know people who actually buy gypsum to put on their fields, and I have this stuff here, so I just as well spread it. I'm gonna borrow a slinger from a neighbor and get it spread, that seems the easiest way to do it. Thanks!
Why recycle drywall?
Here is where it gets interesting, many of the gypsum plants are near coal-burning power plants, and that is because of the process of the scrubbers in the chimneys remove sulfur dioxide from the exhaust of the burned coal.

Many drywall recyclers will provide a dumpster just for drywall, while others set up locations where you can drop your offcuts or your drywall from remodels. They use grinders to break it up into small bits, and magnets to pull out screws, nails, and metal corner beads. It then goes to be filtered where the paper from the faces is screened out to be sent to paper recyclers. It will be used to make recycled paper, and possibly as the paper faces of drywall once again.

The following recommendations should help you avoid problems and use drywall scrap properly as a soil amendment:
What is gypsum filled drywall?
